4. The computer-implemented method of claim 1, wherein each user group of the one or more user groups comprises a user interest group having a corresponding topic of interest.
5. The computer-implemented method of claim 1, wherein each second computing system sends a respective second secret share of the user group identifier for each of the one or more user groups that have centroid that is within a threshold of the user profile of the user.
6. The computer-implemented method of claim 1, wherein the client device generates the user profile of the user based on stored event data for online events associated with the client device.
7. The computer-implemented method of claim 1, wherein first user profile data comprises a first secret share of the user profile data generated using a secure MPC protocol corresponding to the secure MPC process.
8. The computer-implemented method of claim 1, wherein the first computing system stores a first secret share of the centroid for each user group and each of the one or more second computing systems stores a respective second secret share of the centroid for each user group.
12. The system of claim 9, wherein each user group of the one or more user groups comprises a user interest group having a corresponding topic of interest.
13. The system of claim 9, wherein each second computing system sends a respective second secret share of the user group identifier for each of the one or more user groups that have centroid that is within a threshold of the user profile of the user.
14. The system of claim 9, wherein the client device generates the user profile of the user based on stored event data for online events associated with the client device.
15. The system of claim 9, wherein first user profile data comprises a first secret share of the user profile data generated using a secure MPC protocol corresponding to the secure MPC process.
16. The system of claim 9, wherein the operations comprise, wherein the first computing system stores a first secret share of the centroid for each user group and each of the one or more second computing systems stores a respective second secret share of the centroid for each user group.
20. The non-transitory computer readable storage medium of claim 17, wherein each user group of the one or more user groups comprises a user interest group having a corresponding topic of interest.
